Struct ntex_service::dev::ApplyMiddleware

pub struct ApplyMiddleware<T, S, C>(_, _);

Apply middleware to a service factory.

Trait Implementations

impl<T, S, C> Clone for ApplyMiddleware<T, S, C>

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T, S, R, C> ServiceFactory<R, C> for ApplyMiddleware<T, S, C>where
    S: ServiceFactory<R, C>,
    T: Middleware<S::Service>,
    T::Service: Service<R>,

type Response = <<T as Middleware<<S as ServiceFactory<R, C>>::Service>>::Service as Service<R>>::Response

Responses given by the created services.

type Error = <<T as Middleware<<S as ServiceFactory<R, C>>::Service>>::Service as Service<R>>::Error

Errors produced by the created services.

type Service = <T as Middleware<<S as ServiceFactory<R, C>>::Service>>::Service

The kind of Service created by this factory.

type InitError = <S as ServiceFactory<R, C>>::InitError

Errors potentially raised while building a service.

type Future<'f>
where
    Self: 'f,
    C: 'f = ApplyMiddlewareFuture<'f, T, S, R, C>

The future of the ServiceFactory instance.

fn create(&self, cfg: C) -> Self::Future<'_>

Create and return a new service value asynchronously.

fn map<F, Res>(self, f: F) -> MapFactory<Self, F, Req, Res, Cfg>where
    Self: Sized,
    F: Fn(Self::Response) -> Res + Clone,

Map this service’s output to a different type, returning a new service of the resulting type.

fn map_err<F, E>(self, f: F) -> MapErrFactory<Self, Req, Cfg, F, E>where
    Self: Sized,
    F: Fn(Self::Error) -> E + Clone,

Map this service’s error to a different error, returning a new service.

fn map_init_err<F, E>(self, f: F) -> MapInitErr<Self, Req, Cfg, F, E>where
    Self: Sized,
    F: Fn(Self::InitError) -> E + Clone,

Map this factory’s init error to a different error, returning a new service.
